I'm getting ready to place another order from Montana Gold and want to buy a case for the obvious saving $$. I'm going to start reloading 10mm for the first time and my 10mm loads will be just for fun as I don't hunt down here with the G29SF. I also reload for 40SW and have usually loaded 180gr bullets as they're softer shooting. I want to buy the same weight for my 40SW & 10MM loads and I'm torn between the 165gr and the 180gr.

My predicament lies in where I have an MP5 clone in 40SW with a Bolt specific for 165gr loads. Will the 165gr work well for me for both 10mm and 40SW? I currently have Unique, and WSF on hand, but was thinking of getting a 1# of Longhsot or AA#9 for some full power 10mm?

Any help would be appreciated here.

Thanks :wavey:

I'm going to need to order some more bullets for plinking as well. I had originally tried to order 165's but they were back ordered and I took the 180's instead. They work just fine however I was thinking of going with 165's too. I might just get a case of both, as I don't think I could go wrong with either.

I found the 165 grain TMJ 10mm loads with 6.5 grains of Unique (1012 fps) to be very accurate.

I'm still a 10mm newbie, so the main reason I'm chiming in is so I can follow this thread with the "Replies" search function.

I plan to load 250 to 300 more 165 grains and then I'll load 250 to 300 rounds of 180 grain TMJs. I'm just following a couple of reloading manuals that I have which list their most accurate loads.

I have two hundred and fifty 135 grain Nosler hollow points on back order for more nuclear loads.

What OAL are you using? Is this in a G20 or G29?

I'm using a Glock 20 SF.

I was trying to set it up at 1.250, but I ended up at 1.2525.

I also had the same problem deciding which to order and ended up trying some 180 gr. I just got them in the mail yesterday. I figure I'll end up trying some 165 gr next. This is my first go around reloading 10mm so I'm sure over time you'll figure out which one you like best. At least that's what I'm hoping happens to me. I like my 20sf so much I haven't shot my 23 or 27 in months.

That's the way I'm looking at it. I have some Unique to burn up before I try another powder, so I'm glad my first batch turned out so accurate.

I'm putting the same connector into my 20sf that I have in my Glock 34. If my groups tighten up any more, it's going to be a coin toss which Glock is going to the range with me this week. :supergrin: Nice problem to have.

Don't forget about West Coast Bullets. They are plated, but if you are loading up med velocity plinkers, they work great.

Nice thing about them is they offer them 500 at a time, and they have multiple weights.

Yep.

I wonder: Does Montana gold have any reloading data regarding various powders and the velocity attained from them?

I asked them if they knew what their ballistic coefficient for their bullets were and they replied: No. :supergrin:

One thing I noticed about these bullets is that their jackets separate really easy - and they do not expand as well as other bullets (such as xtp) but it won't matter if you're just target shooting with them.

I believe that when you load plated bullets, you should use reloading data for lead bullets.

Q. What if I can't find load data for your bullets?
A. If you have a load for a cast lead bullet, that will transfer across the board as far as our bullets go. We recommend that you reduce
a load for a jacketed bullet by 10%.

Q: Do your bullets have ANY velocity restrictions?

A. In general, our bullets typically perform their best when shot at velocities no greater than 1,200 to 1,250 Feet per second (FPS).

:agree:

I agree with everything stated about plated bullets. I'd also add, load them to the long end of specs (1.26"). Also EEEEEEAAAAAAAASY on the crimp.

For the 180 vs. 165 question, I shoot the 180 grainers at a bit less than supersonic velocities. For volume work, subsonic velocities seem to be a little less harsh to me in terms of percussion etc. An equivalent power factor from the 165 grainers would put them into supersonic (and louder) territory.

I know, I know, that is what hearing protection is for. However, the percussion seems a bit nicer at with the 180 gr bullets. Plus some of you would cry heresy at the thought of running a 180 grainer at less than 1200 fps:whistling:. That is ok too, and I run them up there for certain purposes. But that type of a power factor is a bit much for me in IDAP matches.

I personally love soft shooting 10mm rounds. There's a sweet spot with 180-gr. rounds where it's still supersonic but not near max, but still above anything a .40S&W can do, and it's nice and accurate to boot. So far my favorite recipie is:

180-gr. Sierra FMJ
6.5-gr. Unique
Whatever brass
CCI LPP

That load is just super sweet out of my stock G20. Cuts out the X and the recoil is quite manageable.

At what OAL, I still have some Unique on hand that I can try aside from the WSF that just came in. :supergrin:

Fire medic...I stay with in the 1.250" to 1.260" range with all my 10mm stuff, even the longer ones feed and function from my S&W10xx and Glock 29.

If I load to max powder charge weights I seat to the longer length.

Ok brother thanks for the info.

My bullets are en route and I have Unique and WSF on hand. Just need one more powder for some full power loads, debating between longshot and AA#9.

^^ Me too.

So far, the most accurate load I have made is a Sierra 180-gr. FMJ bullet over 6.4-gr. Unique with a COAL of 1.26". I have some Hornady XTP 180-gr. JHP over 6.6-gr. Unique in my magazine right now awaiting testing. I have a good feeling about them!!!!!

I got a good deal on some 180gr Hornady XTP hollow point loads and will be shooting one of the boxes I got tomorrow or Tuesday. :supergrin:

I've had better luck with longshot and powerpistol.#9 is a good powder for full power but I've had some trouble seating hollow points(compressed loads)?
800x is my favorite right now, but I hand weigh each round. I found some info on barnes 140gr tac-xp bullets with #7. 11gr-13gr max but I havent been able to seat the copper bullet without deforming hollow point with a charge greater than 12gr. 11.8gr is very accurate at an OAL of 1.260.

Heavy for caliber and a bit less speed is more accurate than the opposite. In any question where bullet weight matters I'll suggest as heavy an option as is defensible.
I happen to notice this tendency of heavy for caliber seems to be moreso the older the folks are who are asked. I think that good performance with less stress on the gun, and precise shot placement rather than maximum power, becomes more valued with age.

200 grain for 10mm/.40 is better than the lighter bullets (based on my experience).

I guess because I learned a lot from a bunch of old timers I have the same mentality.

I like the 180gr in the 40 and the 230gr in 45, of the ammo I have shot so far i like the 180 in 10mm also but have yet to shoot any 200gr ammo. That will change in the next day or two as I have a box of DT 200gr controlled expansion HP ammo at home that needs to be shot out of the G29 SF.

I like the heavy for caliber 200xtp/10mm for self defense but would rather have a few light bullets loaded first for in house defense. Barnes x bullets or DPX is a good bullet that doesnt need to be pushed hard to be effective. DPX in 10mm 155gr is 1200fps and in 40cal is 140gr at the same velocity.

I Have made up about 3000 165gr MG's using new Starline brass 9.8gr Power Pistol 1.255 OAL CCI300 primers, crimp at .420 average velocity from my G20sf 4.6 barrel was 1294ft/sec 607ft/lbs energy. Accurate and no problems with pressure ,max published load 10.0 @1.255OAL
I have have loaded to 10.1 grains of PP with no pressure signs but strangely they were 10 ft/sec slower than my 9.8gr loads. Only difference was crimp .421. I imagine if I sat them down to 1.252 or 1.250 and used mag primers I would get about 10 to 20ft/sec more but not worth pushing the envelope for incremental gain in energy.
